Installation and Maintenance Points

1. Pre-Installation Inspection: Confirm that the cabinet space, DIN-rail specifications, and input voltage meet the product requirements.
2. Wiring Specifications: Follow the IEC 60204-1 standard, use cables that meet specifications, and ensure the terminal blocks are securely fastened.
3. Ventilation and Heat Dissipation: The module generates heat during operation, so sufficient ventilation or forced heat dissipation in the cabinet must be ensured.
4. First Power-On Test: After power-on, use the diagnostic software provided by HIMA to check whether the status of each channel and protection functions are normal.
5. Regular Maintenance: Every 6 to 12 months, check the tightness of the wiring, the corrosion of terminals, and the operation status of cooling fans (if any).
6. Fault Diagnosis: Use the built-in monitoring and communication functions to remotely read fault logs and quickly locate abnormalities.
